669073 divided by 81 
We want to figure out the number of times 669073 can be divided by 81.

On to step 1:
81 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 81

Let's proceed to step 2:
When dividing 66 by 81, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (9) from the dividend, add it to 66, then carry on: 669 / 81

Step 3:
81 can be fit into 669 8 times, resulting in a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 648 from 669, we get 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 81

Step 4:
81 can be fit into 210 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 82.0
Subtracting 162 from 210 leaves us with 48.
Fetch the next digit (7) from the dividend, attach it to 48 and continue: 487 / 81

Moving on to step 5:
81 can be fit into 487 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 826.0
Deduct 486 from 487 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 81

Step 6:
81 can be fit into 13 0 times, resulting in a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 8260.0
The remainder is 13 after subtracting 0 from 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
When dividing 130 by 81, we get 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 8260.1
The remainder is 49 after subtracting 81 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 8:
81 can be fit into 490 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 8260.16
Subtracting 486 from 490 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
81 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 8260.16
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
81 goes into 400 4 times with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 8260.1604
The remainder is 76 after subtracting 324 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 11:
When dividing 760 by 81, we get 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 8260.16049
The remainder is 31 after subtracting 729 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 12:
The number 81 fits into 310 3 times, leaving a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 8260.160493
Deduct 243 from 310 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 13:
670 divided by 81 is 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 8260.1604938
The remainder is 22 after subtracting 648 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
If we divide 220 by 81, we get 2 and a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 8260.16049382
The remainder is 58 after subtracting 162 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The quotient of the division is 8260.16049382, and the remainder is 5.8e-08.
